Abstract

In DC breaker, controllable lightning arrester, and other application scenarios, a fast mechanical switch adopts an electromagnetic repulsion mechanism. In the driving process, the peak value of the repulsion force will reach reaches hundreds of kN, which brings a great impact on the transmission mechanism and reduces the life of the mechanism. This paper designs an electromagnetic repulsion device with a dual repulsion disk structure, which can meet the requirements of reliability and redundancy of electromagnetic repulsion mechanisms. The electromagnetic repulsion mechanism has two repulsion disks fixed on the driving rod, and each repulsion disk has a separate driving coil and driving power supply. Compared with the electromagnetic repulsion mechanism with the single repulsion disk structure, the peak value of repulsion shared on each repulsion disk will be reduced by half. It is beneficial to reduce the difficulty of the mechanical strength design of the mechanical transmission structure and can realize the redundant design of the mechanism. The feasibility of the mechanism design and the influence of the main parameters on the mechanism were verified by simulation, and the engineering prototype was finally developed. In this paper, we provide an idea for the design of an electromagnetic repulsion mechanism.
